Figure Legend Snippet: A,B,C) Schematic of constructs used here to activate FGF (A), BMP (B), and Nodal (C) signaling. Myr = myristoylation motif, GS = glycine/serine linker, LOV = light oxygen voltage-sensing domain, HA = hemagglutinin tag, FLAG = FLAG epitope. The single-transcript bOpto-2A-Nodal construct (C) follows the same design as -FGF and -BMP, except the type I (Acvr1ba) and type II (Acvr2ba) components are connected via a 2A peptide sequence (gray). A’,B’,C’) Optogenetic strategy to activate FGF (A’), BMP (B’), and Nodal (C’) signaling. Blue light-dimerizing LOV domains are fused to myristoylated receptor kinase domains. Blue light exposure should lead to receptor kinase interactions, signaling effector phosphorylation, and activation of target genes.
Techniques Used: Construct, FLAG-tag, Sequencing, Phospho-proteomics, Activation Assay
